In terms of runtime performance, how expensive it is to cast int to short in Java? There may be thousands of such casting, hence I wonder if it would impact the performance or not. Thanks.

No. It won’t impact performances. It is a single simple operation.
When you want to analize performances of a software you better focus on the computational cost of algorithmic operations based on the size of input.
